Be it known that W67 Howsnn and irnner'r J the United States. ire-n inthe county of (aail'torcl, State or" arolina. have inrentecl certain newancl useful Improvements in TireFiller-s, oil' which the tollowing is aspecification.

As is Well known, the greatest expenf'e in connection with a motorvehicle is the pneumatic tire owing to toe fact that it easilypunctured, and frequently blows out in hot Weather as the air inthe tubeis heated to a high temperature clue to the friction between the shoeand the surface of the road.

"The object of our invention is to entirely eliminate what. is known astire trouble by producing a tire that is puncture anal blow out proofand. at the same time pro" rides a cushion eti'ect equal to air.

Gar invention consists in a. certain C0111- aiiaptecl to be poured in arubber position being far superior to rubber as it will. not clecaf ifreeze, dry out, because harcl with age; or lose its resilient qualitiesuncler any condition.

The illustration is a transverse sectional View of a tire embodying ourinvention.

Our invention consists primarily in a filler for rubber tire tubescomposed. of pulverized cork or any light material such as saw-(lust,Wood pulp or the like. sulfur and corn oil. Of the light materials weprefer to use pulverized cork. The preferrecl composition consists of 1part pulrerizecl cork 8.5 parts sulfur; 30.5 parts corn oil.

It will of course be unclerstood that we may vary the proportions ofingredients and the temperatures given, more or less. The method ofcompounding; our ler as follows: T he corn oil is iii temperature oifrom 310 t (more or less), then th this composition. is kep ture for aperil-o5. cork (or other light Ina.
